Everything You Need to Know about Dental Crowns

Oct 01, 2020

A dental crown is a cap in the shape of a tooth that is usually fitted over your tooth for purposes of restoring its size, shape, or strength and improving its appearance. Once cemented into place, the crown fully encases your tooth’s visible portion lying above your gum line.

Why you need a Dental Crown

You may need a tooth crown to:

  • Protect teeth that have been weakened, for instance, by decay from breaking
  • Hold together bits of a cracked tooth
  • Restore a broken tooth or a severely worn down tooth
  • Cover and support small portions of teeth with large fillings
  • Hold dental bridges in place
  • Cover discolored or misshapen teeth
  • Cover dental implants
  • Make cosmetic modifications

Dental Crowns for Kids

Children’s primary teeth may need a crown to:

  • Save a severely decayed tooth that can’t support a filling
  • Protect the child’s teeth from tooth decay.
  • Reduce the frequency of administering general anesthesia to kids that can’t practice proper oral hygiene.

In these cases, our Jackson Heights dentist may recommend stainless steel crowns.

Types of Dental Crowns

Tooth crowns are classified according to the type of material from which they are made. Here are the common types of dental crowns in Jackson Heights:

  • Stainless Steel Crowns: These prefabricated crowns are used temporarily on permanent teeth. Typically, they protect your filling or tooth before your permanent crown is completed. In children, these crowns are fitted over primary teeth. The crown conceals the whole tooth preventing further decay. When the time comes for your kid to shed off their primary tooth, the crown comes out with it.Generally, our dentist at Smile Dental Group recommends stainless steel crowns for kids as they are cost-effective and need fewer visits to the dentist’s office.
  • Metal Crowns: Some of the metals used in crowns include base-metal alloys and alloys with high platinum or gold content. Metals can handle forces resulting from chewing and biting. Also, they do not wear down easily, so you’re assured of longevity. Chipping or breaking is uncommon in these crowns, and they are suitable for the tooth at the back of your mouth.
  • Porcelain-fused-to-metal Crowns: Unlike their metal counterparts, these crowns can be customized to match the color of your natural teeth. They are a good choice for both your front and back teeth.
  • All-resin Crowns: Compared to other crown types, these are less costly. Their only drawback is their susceptibility to wear and fractures.
  • All-porcelain Crowns: They bear a very close resemblance to your natural teeth and are suitable for individuals with metal allergies and other sensitivities. Besides, they can be fitted over any of your teeth.

Dental crowns can also be classified as permanent or temporary. While temporary crowns are designed and developed in the dentist’s office, permanent crowns are made by technicians in dental laboratories. Our Jackson Heights dentist will fit a temporary crown made of acrylic-based materials or stainless steel before your permanent crown is ready.

Preparing a Tooth for Crown Fitting

Two steps are involved in tooth preparation for dental crowns. The first one involves tooth examination and preparation, while the second involves the permanent crown’s fixation.

These are some of the things to expect during your first visit:

  • The dentist takes x-rays to examine the tooth roots and the surrounding bone carefully. When they notice extensive decay, your dentist will perform root canal therapy first before proceeding.
  • Your dentist administers anesthesia to numb the tooth and the surrounding gum tissue.
  • The affected tooth is reshaped along the sides and chewing surfaces to receive the crown.
  • The dentist makes an impression of the affected tooth using putty or a paste.
  • Your doctor sends the impressions to a dental laboratory for your permanent crown to be manufactured.
  • A temporary crown is fitted over the prepared tooth.

On your second visit, the dentist removes the temporary crowns and checks if the permanent crown fits properly. If everything is okay, they will administer local anesthesia before cementing the permanent crown in place.

Complications Associated with Dental Crowns

It is not uncommon to experience these complications after getting dental crowns in Jackson Heights.

  • Discomfort: You will experience some discomfort and sensitivity as the anesthesia wears off.
  • Chipped or Cracked Crown: Porcelain crowns sometimes chip or crack. A small chip can be easily fixed, but an extensive one requires crown replacement.
  • Loose Crown: They occur when the cement fixing the crown in place is washed out.
  • Crown falling Off: This may result from cavities in the tooth beneath or loosening of the cement.
